The project was completed to the customer’s satisfaction, with significant lost project time recovered.
However, operating a CO2 capture unit in the Wisconsin winters presented special challenges.
The teams worked together, customer and Koch Modular, to resolve a few unique operating issues resulting in a successful test program.
When the same customer needed a partner to build a larger carbon capture unit in a West Virginia power plant, Koch Modular was the logical choice.
With its own expertise and the experience gained from the Wisconsin project, Koch Modular designed heattraced, free-draining piping with no stagnant areas. For high temperature corrosion areas, higher alloys instead of 316SS were used.
Because this project was also scheduledriven, modular construction was recommended to meet the schedule. This allowed the power plant to limit their on-site labor, and focus on off-module engineering, and other infrastructure, while Koch Modular handled the design and construction off-site.
The Koch Modular unit was the first to be completed within the larger Carbon Capture pilot project. The pilot unit was run by the power utility for two years to test the concept – up to 300 tons a day of CO2 was compressed, injected and sequestered between layers of rock deep underground. The project was deemed a complete success(1).
